CONVERTIBLE WINDOW-SASH.

Specification of Letters Patent.

Patented Jan. 7, 1908.

- Application filed March 3, 1906. Serial No. 303.968.

To all whom t may concern:

Be it known that I, HARRY J. FoLTz, a citizen of the United States, residing at Akron, in the county of Summit and Stateof Ohio, have invented certain new and useful Improvements in Convertible Window-Sash; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to convertible window sashes, and has for its object the forming of the stiles of the sash, at both sides, in two parts one ofthe parts engaging the window traine, and the other part .being pivotally secured to the sliding portion, the lower being arranged in such a manner that the win,-

. dow, while adapted to slide in its ways in the window frame, can be rotated, or, more properly speaking, operated so as to swing inward and outward on its pivotal connection, thus allowing the opening of the window in this manner for the purpose of cleaning it, and its glass on the exterior, and eliminating the danger resulting from the necessity of exposing the person on the outside of the building, and the liability of falling, or otherwise injuring the person.

Another object of my invention is to so unite the two parts ofthe stiles of the sash that while pivoted together in such a manner that the portion that holds the glass can be operated at any suitable angle for Ventilating pprl poses, or entirely reversed for cleaning tir-fi poses, the joint formed by the division o the stiles is sealed or overlapped by a dev1ce which also forms a locking mechanism, to

- hold the two parts firmly in alinement.

Still another object of this invention is to simplify the construction so that any ordinary person can easily understand and manip-v ulate it.

Vith the above objects in view, my invention consists in dividing the stiles of a window sash, and providing a locking means for alining both parts.

My invention further consists in providing a divided sash frame with locking means which will aline both parts and over-lap or seal the dividing line or joint.

My invention still further consists in the construction and details of construction which will be hereinafter fully set forth and claimed.

In the drawingsfigare is an isometrif sliding portion E, connected preferably to i view of a portion of a windowframe, and a portion of the upper and lower sash, illustratl ing the construction and application of my invention when the `same is constructed and assembled according to my invention. Fig. II is a cross sectional view taken through the pivotal connection between both parts of the sash-frame, showing more clearly the manner of assemblage, operation, and connection .of the parts when the same is constructed as illustrated in Fi I. Fig. III illustrates the parts of the saslh, with the ortion holding the glass swung at an ange to the other portion.

A represents the pulley piece, with the upper parting strip A', and the inner beading B, which may be of any suitable construction or arrangement. This frame A does not constitute any part of my invention excepting .as a means for retaining the sash in osition, and if necessary allowing the sas to be raised or lowered, and hence in certain cases the parting strip A and the pulley iece A with the other auxiliaries, may e dispensed with.

Theimportant feature of my invention is embodied in the sash itself.

C represents that part of the sash which engages the window frame, either in a stationary manner or so as to be raised or lowered.

C represents that part of the sash within which the lglassG of the window is held.

The parts O, C are separate, being joined together bya pivot P, (see Fig II,) 'of suitupper sash or raising the lower sash, so as to free them from the u perI and lower jams of the window frame, tlliat the upper sash can be swung inward and thence downward, and reversed to the extent of resenting the top face of the glass which is orrnerly of the eX- terior of the window, inward for the purpose ofcleaning it.

In order to form a sash which has all the advantages of an ordinary sash, besides the advantages hereinbefore mentioned, I have provided a locking means which comprises a able formationto allow the inner (portion C',

as illustrated in I, that, by lowering theV iso the portion C of the sash; this piece E being shown in the drawings and rovided with elongated slots e, e, and bin ing screws F, which pass through the slots and from thence into the ortion C of the sash in such a manner t at they may be loosened and tightened and thus loosen and tighten the sliding piece E. It will be observed by reference to the drawings that the slide E is so formed that when it is slid to the joint c, it will overlap the same and bind the sash parts C, C into alinement.

In order to further provide a erfect lock and sash, I have provided, as il ustrated in the drawings, a keeper-piece K which flares or projects in from the piece C, at its inner face in such a manner as to receive the slide piece E. The juncture or meeting portions of the two pieces Eand K being so formed 'that a sealed connection is provided between them. This sealed connection erforms the double function of preventing t e rattling of` the parts in relation to each other and forming a perfect dust and air seal.

The parts E and K may be formed in any suitable manner so that they will interlock in the manner, and for the purpose above set forth, and it is obvious that certain of these parts and their relation to each other may be modified, as may also other details, such as the pivot pin p, and I do not wish'therefore to limit my invention to the construction shown and hereinabove set forth.

In the construction of a sash of the t e hereinabove set forth and shown in t e drawings, many apparent and obvious advantages are attalned, as its simplicity of construction and perfect operation of the parts, eliminating complicated devices and operations. 40

As hereinabove set forth, while I have shown and described my invention as applied to a double 'sash window, and I have shown details of construction as I consider them best adapted to perform that function in relation to each other, I do not wish to be limited to these details, which as hereinabove stated can and will be modified to adapt them to position and circumstances.

A slidabl'e and tiltahle windowsash having its'stiles divided vertically into outer sliding members and inner tilting members, a pivot connecting each pair of mem ers, a keeper of each sliding member and having its inner longitudinal portion flared away therefrom, and a transversely slidable locking strip mounted longitudinallypn-threaf Aside of each tilting member, being arranged in lock- 60 ing position to overlap the two members and engage tightly behind the flared portion of said keeper stri Signed at CIeveland in the county of Cuyahoga and State of Ohio, this 26 day of G5 August, 1905.
